An openmodelica package for BELBIC
Coelho, João Paulo; Coelho, J. A. B.; Braz-César, ManuelThis paper presents the development and implementation of a new package for OpenModelica that integrates the Brain Emotional Learning Based Intelligent Controller (BELBIC) approach into control system simulations. BELBIC, inspired by neurobiological models of emotional learning, has demonstrated effectiveness in handling complex, nonlinear, and adaptive control problems. The proposed package provides a modular ...

Laser Engraving for 3D Surfaces: A Robotized Application Case Study
Alvarez, Mariano José; Brancalião, Laiany Suganuma; Carneiro, Jorge; Costa, Paulo; Coelho, João Paulo; Gonçalves, JoséOne of the industry’s most common applications of lasers is engraving, which is generally performed on flat surfaces. However, there are many situations where the object to be engraved has an unevenly curved geometry. In those cases, the light power density will be different along the surface for a fixed head, leading to a poor engraving result. This work deals with this problem by designing a robotic applicati...
Prototyping and Control of an Educational Manipulator Robot
Coelho, João Paulo; Brancalião, Laiany Suganuma; Alvarez, Mariano José; Costa, Paulo Gomes da; Gonçalves, JoséThis article presents the prototyping of an educational manipulator robot, based on the “EEZYbotARM Mk2” robot, tailored for first-year master’s students in the field of robotics. The project encompasses the assembly of the robot arm, computation of both forward and inverse kinematics, and analysis of two path-planning movement algorithms. These features are consolidated into an Arduino library to streamline th...
Chain of Trust: Integrating IoT and Blockchain to Certify Wild Mushroom Growth ...
Rosse, Higor Vendramini; Camargo, Caio; Gonçalves, Estefânia; Sabiri, Khadija; Coelho, João PauloThis paper presents the preliminary results of the study developed within the scope of the ”Safe2Taste” project presenting the main concept of hardware and software architectures. The project aims to build a monitoring system supported by IoT technologies and covered by a security layer through interaction with a blockchain network to be applied in an edible mushroom production system. The hardware and software...
Programming Mobile Robots in an Educational Context: a Hardware-in-the-loop App...
Brancalião, Laiany Suganuma; Alvarez, Mariano José; Coelho, João Paulo; Conde, Miguel Ángel; Costa, Paulo Gomes da; Gonçalves, JoséIn this paper it is presented a Hardware-in-theloop (HIL) mobile robot programming approach, to be applied in a robotics educational context. The motivation to apply this approach is the fact that students can program the robots without access to the robot hardware, but still maintain some important closed loop control critical features, such as a realistic lag time and the possibility for a larger number of st...
Static analysis of a lamppost according to Eurocode EN-40
Gonçalves, E.S.; Gonçalves, J.; Rosse, Higor Vendramini; Costa, José Joaquim; Jorge, Luisa; Gonçalves, José; Coelho, João Paulo; Ribeiro, J.E.When people move around a town, at some point in their journey they need to cross the road using a dedicated crosswalk. However, crossing is not always done safely due to weather conditions, lack of visibility or distraction. The VALLPASS project, aims to install two lampposts in opposite positions to the direction of crossing, with various functionalities and technological innovations, creating a luminous tunn...
